If you're using PGXS, then yes, your makefile should be querying
pg_config to find out where Postgres' headers etc are installed.
You might want to check whether "pg_config --pgxs" points to the
correct place.  Also make sure your makefile is indeed doing
something like

PG_CONFIG = pg_config
PGXS := $(shell $(PG_CONFIG) --pgxs)
include $(PGXS)

and not just hard-wiring where to look.
